I am writing a Windows application that needs access to the high-level 3270 API (EHLLAPI). I need to be able to use two 3270 packages (ie, offer two alternatives): Attachmate and Rumba. I know that under Win 3.1, these comms packages can give Windows applications access to the API (Attachmate does it via a DLL that you have to install after installing the main Attachmate package). I assume that they are doing this via some kind of interrupt. Do you know whether it will continue to work under Win32s? Are the same interrupts supported? If they needed shared memory as well, would that work? Thanks Gerry There are 2 Replies.

Gerry, NT will use its own SNA stack, but each ISV will provide the 3270 emulation and HLLAPI. It will be up to these vendors how they handle WIN32s. I have access to their private forum and will post the message there. Carl

They don't use interrupts. Each vendor uses a differently names DLL with the entry point "hllapi" defined. We got this working recently by using msft's thunking routines to call this entry point with thunked arguments. Dave Kolb SAS Institute
